The invention provides an air conditioner indoor unit and an air conditioner comprising the same. Regarding the indoor unit of the air conditioner, the following suspended indoor unit is described as a specific embodiment.
Referring to fig. 1 to 5, the indoor unit 10 of the air conditioner includes a housing 11, a through-flow wind wheel 12, a heat exchanger 13, a water pan 14 and a volute assembly 15, wherein the housing 11 includes a front panel 11a and a bottom plate 11b, an air outlet 110 is disposed on the front panel 11a, and an air inlet 111 is disposed on the bottom plate 11 b. The heat exchanger 13 is located substantially below the cross-flow wind wheel 12, and wraps the cross-flow wind wheel 12 in a semi-enclosed manner. The water receiving tray 14 is located below the heat exchanger 13 and is used for receiving condensed water formed on the surface of the heat exchanger 13. The volute assembly 15 is formed with an air outlet duct 150, and the air outlet duct 150 is in butt joint with the air outlet 110. The first air deflector 16 is installed at the air outlet 110, and the first air deflector 16 can rotate, so that the air outlet angle can be adjusted. The panel 11a is further provided with a second air deflector 17, and the second air deflector 17 can rotate to further adjust the air outlet angle, and on the other hand, when the air conditioner stops running, the second air deflector 17 can cover the air outlet 110, so that dust or other sundries can be prevented from entering.
The heat exchanger 13 may be a V-shaped heat exchanger, a tri-fold heat exchanger, or a flat plate heat exchanger. For a V-shaped heat exchanger, the lower end thereof may extend into the drip pan 14; for the three-fold heat exchanger, the heat exchanger comprises a straight section 13a and vertical sections (a front evaporator and a rear evaporator) arranged on two sides of the straight section 13a, wherein the two vertical sections can be vertically upwards extended or upwards obliquely extended, and the straight section 13a is horizontally paved right above the water-saving disc.
The water pan 14 includes a pan bottom 14a and a plurality of blocking portions 14b disposed on the pan bottom 14a and extending along a length direction of the water pan 14, the blocking portions 14b are sequentially arranged along a width direction of the pan bottom 14a, and each blocking portion 14b is laterally opened to form an air passing gap 144, where the air passing gap 144 may be opened on a front side and/or a rear side of the blocking portion 14b, or may be opened on a left end side and/or a right end side of the blocking portion 14 b. The following will describe in detail an example in which the air passing gap 144 is provided at the front and rear sides of the blocking portion 14 b. The bottom of each blocking portion 14b is provided with a through hole 145 penetrating the tray bottom 14a and communicating with the wind passing gap 144.
The bottom plate 11b includes two sub-bottom plates 11b located at two sides of the water tray 14, and the air inlets 111 are disposed on the two sub-bottom plates 11 b.
The water receiving tray 14 includes, in addition to the tray bottom 14a, coamings 14c attached to both sides of the tray bottom 14a, and end plates provided at both ends of the tray bottom 14 a. The end plates, the coamings 14c and the tray bottom 14a together form the basic structure of the water tray 14. The blocking portion 14b extends along the length of the tray bottom 14a and divides the drip tray 14 into a plurality of sections. The number of the air passing gaps 144 formed laterally at the upper end of the blocking portion 14b may be plural or one, and for the embodiment of the air passing gaps 144, the air passing gaps 144 are arranged at intervals in the length direction of the blocking portion 14 b.
In order to fit the installation of the heat exchanger 13 and also to reduce the manufacturing cost, the blocking portion 14b is preferably provided to extend continuously (without interval) in the length direction of the tray bottom 14a, and both ends thereof are directly connected to both end plates. The barrier 14b allows on the one hand the external air flow to pass through and on the other hand also supports the heat exchanger 13.
The three-fold heat exchanger 13 can be directly arranged on the shell 11 and hung on the water pan 14; or two side plates or top plates whose upper ends are connected to the housing 11, and whose flat sections 13a are supported by the blocking portions 14b of the drip tray 14. Thus, when the indoor unit 10 of the air conditioner is operated, air under the water pan 14 can pass through the water pan 14 along the through hole 145 and enter the heat exchanger 13 to rapidly exchange heat.
Because the front and rear sides of the water pan 14 are provided with the air inlets 111, when the air is taken in by the air inlets 111 on the front side of the water pan 14, the surrounding air is sucked, including part of the air near the front panel 11 a. Thus, when the air conditioner performs the heating function, the vacuum degree generated by the air inlet 111 at the rear side of the air outlet 110 deflects the air flow direction flowing out of the air outlet duct 150 downward (for example, 2 ° to 3 °), so that the vertical air supply distance of the warm air can be increased.
Through testing, after the water pan 14 is used for replacing a common water pan, the air output in unit time is increased by 5% -10% at the same rotating speed, and the average air output is increased by 8.2%; the noise of the same air quantity is reduced by 1-2 dB, the average noise is reduced by 1.6dB, and the vertical air supply distance of warm air is increased by 0.26-0.30 m.
According to the technical scheme of the invention, the plurality of blocking parts 14b are convexly arranged on the tray bottom 14a of the water tray 14, the upper end side of each blocking part 14b is provided with the air passing gap 144, and the bottom of each blocking part 14b is provided with the through hole 145 which penetrates the tray bottom 14a and is communicated with the air passing gap 144, so that the water tray 14 can not only receive condensed water formed on the surface of the heat exchanger 13, but also can allow outside air to pass through, thereby reducing the wind resistance of the outside air entering the air conditioner indoor unit 10, improving the air output and the energy efficiency, and further improving the air supply distance of the air conditioner indoor unit 10. In addition, (1) the air inlet area of the bottom plate is increased, the air quantity under the same rotating speed is improved, and the noise under the same air quantity is reduced; (2) Under the condition of limiting the size of the machine body, the three-fold heat exchanger can be placed (generally, the two-fold V-shaped heat exchanger is placed), the area of the heat exchanger is increased, and the air conditioning capacity is improved.
Specific embodiments of the barrier will be described in detail below.
Referring to fig. 4, in an embodiment, the blocking portion 14b includes a blocking plate 141 (the lower end of the blocking plate 141 is connected to the tray bottom 14 a) extending obliquely upward, and a water stop plate 142 located on the oblique side of the blocking plate 141, the upper end of the blocking plate 141 is located above the upper end of the water stop plate 142, the wind passing gap 144 is formed between the upper end of the blocking plate 141 and the upper end of the water stop plate 142, and the through hole 145 is formed at the corresponding tray bottom 14a between the blocking plate 141 and the water stop plate 142. Here, the water blocking plate 142 may be vertically extended upward or may be inclined upward.
With continued reference to FIG. 4, in this embodimentAdjacent two baffle plates 141 are inclined in opposite directions, and two water-stop plates 142 between the two baffle plates 141 extending in opposite directions are enclosed with the tray bottom 14a to form a first water receiving tank C 1 . The barrier plates 141 are divided into two types from the rear to the front, the first type is inclined forward, the second type is inclined backward, and the two types of barrier plates 141 are alternately distributed from the rear to the front. The two baffles 141 that are inclined relative to each other are: a first barrier 141, and a second barrier 141 positioned in front of the first barrier 141. The baffle plate 141 has high supporting strength and better supporting effect on the heat exchanger 13.
After the condensed water is formed on the surface of the heat exchanger 13, the condensed water drops to the upper end of the blocking portion 14b, and part of the condensed water flows to the lower surface of the blocking plate 141, so that the water receiving tray 14 is water-leaked.
With continued reference to fig. 4, in order to further avoid water leakage, in this embodiment, a support plate 143 extends laterally from the upper end of the baffle 141, and the support plate 143 supports the heat exchanger 13. The support plate 143 extending laterally is understood to extend in a direction substantially parallel to the bottom plate 11b, and it is preferable that the end of the support plate 143 is slightly inclined downward, so that the occurrence of water leakage is substantially prevented.
The user experience will be severely affected by the air conditioner leaking water. On the basis of the above embodiment, in order to further avoid the occurrence of water leakage, it is ensured that the condensed water dropped to the support plate 143 flows to the first water receiving tank C 1 When flowing, the water can flow to the first water receiving tank C 1 In this embodiment, the first water receiving tank C is located at the same position 1 The distance between two adjacent support plates 143 above is smaller than the distance between two adjacent support plates forming the first water receiving groove C 1 Is provided between the two support plates 143.
Referring to fig. 6 to 10, unlike the above embodiments, in the present embodiment, the barrier plates 141 are all inclined in the same direction, and the inclination direction of the water stop plate 142 is opposite to the inclination direction of the barrier plates 141.
Although the blocking portion 14b has a general supporting strength for the heat exchanger 13 in the present embodiment, its water receiving space is larger than that of the previous embodiment. And the contact area between the blocking part 14b and the heat exchanger 13 is small, so that the heat exchange efficiency is better.
On the basis of the above embodiment, also, in order to further avoid the occurrence of water leakage, the baffle plate 141 is laterally extended with a support plate 143, and the support plate 143 supports the heat exchanger 13. The structure of the support plate 143 and its extension are the same as those of the previous embodiment.
Referring to fig. 8 and 9, since the air conditioner is affected by the vibration of the motor when it is operated, the heat exchanger 13 is also vibrated. The water pan 14 plays a supporting role on the heat exchanger 13, and the water pan 14 (supporting part) is inevitably worn by long-term vibration of the heat exchanger 13, so that the water pan 14 has high requirement on the supporting stability of the heat exchanger 13. On the basis of the above embodiment, in order to improve the supporting effect of the water tray 14 on the heat exchanger 13, that is, the blocking portions 14b are disposed on the tray bottom 14a, two adjacent blocking portions 14b are connected. I.e., the lower ends of the barrier plates 141 of the adjacent two barrier portions 14b are connected to the lower ends of the water barrier plates 142. In this way, on the one hand, the strength of the whole water pan 14 for supporting the heat exchanger 13 can be improved, on the other hand, the process molding is facilitated, and on the other hand, the deformation resistance of the baffle plate 141 can be improved (besides the involvement of the pan bottom 14a, the involvement of the water baffle plate 142 is also influenced after the connection of the water baffle plate 142)
Referring to fig. 9, in order to increase the water capacity of the water tray 14, in a preferred embodiment, a first water baffle 146 extending along the length direction of the tray bottom 14a is protruded on the upper surface of the baffle 141, the first water baffle 146 is connected to two end plates, and the baffle 141, the first water baffle 146 and the two end plates enclose a second water receiving tank C 2 。
In order to ensure the water receiving effect of the water receiving tray 14 and to avoid the water flow in the water receiving tray 14 from overflowing, the height of the two enclosing plates 14c is higher than that of the blocking part 14 b. However, when the water level in the drip tray 14 is high, water may leak from the overwind gap 144 on the one hand; on the other hand, the dropped condensed water may splash out and leak out from the air passing gap 144. After the first water baffle 146 is arranged, the second water receiving tank can bear part of condensed water, so that the water receiving capacity of the water receiving disc 14 is improved.
Although the first water deflector 146 may increase the water receiving capacity of the water receiving tray 14, the level of the first water deflector 146 is not too high because, when the level of the first water deflector 146 is higher than the level of the surrounding plate 14C, if the water is received by the second water receiving tank C 2 When more condensed water is received, the condensed water can flow outwards, so that water leakage accidents are caused.
If the level of the first water baffle 146 is lower than the level of the shroud 14C, even the second water receiving groove C 2 The water overflows and flows to the inner side of the water receiving disc 14, so that water leakage accidents are avoided.
With continued reference to fig. 9, in order to further increase the water capacity of the water-saving tray, a second water baffle 147 extending along the length direction of the tray bottom 14a is protruded on the upper surface of the water-stop plate 142, the second water baffle 147 is connected to two end plates, and the blocking plate 141, the second water baffle 147 and the two end plates enclose a third water receiving tank C 3 . Also, the second water blocking plate 147 has a lower level than the water blocking plate 142.
In the above embodiment, the water tray 14 is installed in various manners, for example, the bottom plate 11b further includes a support plate 143 disposed between the two sub-bottom plates 11b and connected to the two sub-bottom plates 11b, the water tray 14 is installed on the support plate 143, and an air inlet (not shown) is formed in the support plate 143 and is communicated with the through hole 145. In order to avoid condensation at the bottom of the water pan 14, a heat insulating layer (not shown) may be disposed between the support plate 143 and the pan bottom 14 a. In addition, the support plate 143 may be detachably connected to the two sub-base plates 11b for facilitating the disassembly and cleaning of the water tray 14. For example, the water receiving tray 14 is fixed to the support plate 143, and the support plate 143 is mounted to the two sub-base plates 11b by screws. In addition, the bottom plate 11b and the water receiving tray 14 may be integrally formed.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
